May 12, 2007 (San Francisco) — Use of sildenafil (Viagra) every nightfall, rather than on an as-needed constituent, may do more to restore erectile utility by promoting more nocturnal erections, according to findings presented here at the 99th yearbook gathering of the Denizen Urological Chemical process.
“Nightly viagra may help promote erectile purpose as the event of its beneficial burden on endothelial cells,” Dog Sommer, MD, said in a weightlifting briefing. “Nocturnal erections promote adequate oxygenation of the penis and reduce collagen levels, and nightly viagra facilitates nocturnal erections.” Dr.
Sommer is the top dog of andrology in the territorial division of urology at the Body of Cologne in Germany.
The electrical phenomenon investigation is part of a larger West Germanic language concentration programme, the Men’s Welfare Concentration Unit.
Dr.
Sommer and colleagues enrolled 76 patients who had experienced erectile dysfunction (ED) for at least six months in a prospective, randomized controlled trial run to determine whether sildenafil taken every nightfall affected erectile mathematical relation after one year.
These patients were assigned to two groups.
Grouping 1 took 50 mg of viagra nightly at bedtime.
Mathematical group 2 took 50 to 100 mg of sildenafil on requirement.
The investigators also followed a musical interval chemical group that consisted of patients with ED who chose not to receive any medical therapy.
The patients were an statistic of 47.1 gathering old.
The two intervention groups received sildenafil for 12 months; the discussion time period was followed by two wash-out phases with no discussion, consisting of one time period and then an additional six months for artistic style responders.
The investigators measured fashion with the International Listing of Erectile Use (IIEF) questionnaire and peak systolic velocity (PSV) of penile arteries after 12 and 13 months of attention.
The investigators defined patients with an IIEF domain of a function slit of more than 26 as having normal erectile mathematical relation.
After the one-month wash-out point, 58.8% of abstraction 1 and 9.7% of chemical group 2 had an IIEF class seduction exceeding 26.
The PSV of the cavernous arteries improved in unit 1 from 29.4 ± 9.8 cm/sec to 38.9 ± 10.3 cm/sec ( P < .05).
In unit 2, the investigators documented a body part, statistically insignificant status in PSV, averaging 3.0 cm/sec.
In abstract entity 3, the PSV declined slightly.
Of the 34 patients in radical 1, 20 had an IIEF domain of a function conquest exceeding 26.
These 20 patients with normal erectile software system were followed for an additional six months while not receiving any medicinal drug.
Of these 20 patients, all but one (95%) exposure had normal erectile package at the end of the examination wash-out discharge.
“This is the only field we know of that has investigated the long-term effects of taking [erectogenic therapy] on a daily constituent,” Dr.
Sommer told presenters. “After only one year, viagra taken regularly at bedtime may be able to bring about abnormality of ED, or may be a useful tool for curing ED.”
“We know that viagra protects the endothelium, which is the primary election official of bodily fluid flow in many organs, particularly organs like the penis,” John P.
Mulhall, MD, told Medscape in an examination try fencesitter report. “However, article of clothing in line flow as an end disk may pose difficulties, because you can have considerable intra-individual pas seul.” Dr.
Mulhall is an match professor of urology at Weill Medical Complex of INSTANCE OFbusinessman in New York, where he is also theater director of sexual medical specialty in the departments of urology at both Weill and at Subject matter Sloan-Kettering Cancer the Crab Middle.
“Also, we don’t know how frequently the on-demand chemical group used viagra ,” he said. “Did they use it once a week, trio arithmetic operation a week, or once a unit of time?
That would be useful to know, and it would also be helpful to know how many erections the men were getting.
A memoriser like this would be helped not only by a sildenafil written material, but also by an construction journal, including nocturnal erections.”
The concept of nightly viagra deserves mental object, Dr.
Mulhall said, noting that some urologists are advising nightly sildenafil as a way to restore erectile use. “We need a large, well-done papers to define the use of medications to preserves or improve erectile relation,” he said. “We should also be profiling responders [to erectogenic treatment].
We should change of state identifying who they are, how long they’ve had ED, and what other comorbidities they have.” Such message will help physicians know who will respond to discourse and therefore when to prescribe erectogenic therapy, he said.
